October 25, 2016/October 27, 2016 SPECIATION
- The evolution of genetic barriers to allele exchange among populations. A lot
of scientists have focused on what causes speciation, once it happens and its
forever and ever. The lineages keeps
- adaptation: has to do with the individuals in the wild and the traits they have and what happens to
them if they have the trait or don't have the trait. This is the result of natural selection; will be the death
of a lot of animals.
Biogeography November 1, 2016
-This field is divided into two categories
Historical Biogeography-very typically phylogenetic evolutionary trees,
things that happened millions of years ago, geology, fossil record
Are all traits adaptive? No, its unlikely that all traits are adaptive in all major sense.
Many traits, many genes, amino sites, nucleotide sites are not adaptive but they can
flip around mutations and not have any af
